TiA (TOBI interface A) is a proposal for a standardized interface to transmit raw biosignals, with a focus on BCI (brain-computer interface) systems.
- Multirate transfer
- TCP or UDP data transmission possible
- Block-oriented transfer
- Division into various signal types
- Multiple clients
- Low resource requirements
- Exchange of meta-information between client and server
- Currently in development: Connection based channel selection and downsampling
The TiA library is written in C++. The Code is available here. To get r/w access to the TiA repository, please get in touch with: Christian Breitwieser -- c.breitwieser(at)tugraz(dot)at
Building the TiA library
Linux & Co.
Under a Linux or Unix based distribution, the TiA library is utilizing the qmake build system from the Qt library. The respective '.pro' and '.pri' files (qmake config files) are included in the SignalServer repo. It is suggested to use the Qt Creater as an IDE under Linux, as it fully supports qmake.
The TiA library source is shipped with a Microsoft Visual C++ 2010 solution file (.sln) and the needed project files (.vcxproj) to build the SignalServer. This solution files are also suitable for the Visual C++ Express Edition.
TiA library dependencies:
boost-libs: system, thread, date_time
Using Linux, those libraries are usually included in the repositories of the respective distributions.

The authors are grateful to Christoph Eibel, who spent many hours refactoring the whole TiA communication and also to Andreas Schuller, who wrote the very first version of TiA.
